21 Questions
What is the main goal of software testing according to the text?
To eliminate faults as early as possible
Why is software testing becoming increasingly important?
To prevent software failure
What is the implication of the statement 'Software failure may kill people' mentioned in the text?
Software failures can have severe consequences
What can we learn from software failures?
Software failures need effective testing to be avoided
How does the text describe the cost of late testing?
Prohibitively expensive
What is emphasized as one way to assess dependability in software?
Performing better software testing
Why is it essential to improve software requirements, design, and process according to the text?
To mitigate the risk of software failure
'Better project management' is listed as a way to mitigate software failure risk. What other factor is highlighted in a similar context?
'Better software testing'
'Testing is one way to assess dependability.' Based on this statement, what role does testing play in software development?
'Testing ensures dependability'
What is the relationship between faults, errors, and failures in software development?
Faults lead to errors which cause failures
In software testing, what does 'Bug' refer to according to the text?
A defect informally used to describe issues in the software
In the context of software testing, what is a 'Software Fault' as described in the text?
A static defect in the software
How are software faults related to design mistakes in hardware?
Software faults are similar to hardware design mistakes
What is the significance of 'Software Failure' in the context of software development?
An incorrect behavior that deviates from expected requirements
How does testing contribute to understanding software dependability according to the text?
Testing can help assess and improve the dependability of the software
In the provided code snippet, what is the purpose of the 'lastZero' method?
To return the index of the last occurrence of the number 0 in the array x.
What would be the expected output when using test case x=[2, 3, 5]; y = 2 in the 'firstZero' method as per the code snippet provided?
-1
What could be a potential test case that does not execute the fault mentioned in the code snippet?
x=[1, 0, 1]
Which statement accurately describes a situation where a test case executes the fault but does not result in an error state?
The 'firstZero' method returns an index other than -1 for test case x=[0].
What would be a suitable test case to identify a scenario where an error occurs but not a failure in the given code snippet?
x=null
Based on the provided information, what could be a plausible outcome when running test case x=[2, 3, 5]; y = 6 in the 'firstZero' method?
-1
